Hello Folks

Just joined, hope to learn alot here, I have an English Mastiff / Bull Masttif about 9 months old, Brindle color.

My vet has been calling me to neuter him now, I have read here some posts on the pros and cons of the procedure and I keep seeing mention that they should be at a Mature stage if you are going to proceed with it.

So my question never having owned a dog as large as he is, at what age are they MATURE?

Is is based on age, canines growing out? or other factors?

By the way he is the most Loveable, and well mannered puppy I have ever had, all but the chewing up his ceder dog house which now has a large BAY window Shocked

Thanks for any info.

Yours in Mastiif, The Kraken

Welcome to MOC!! I'm kinda in the same position.
My brindle boy is 2 yrs and hasn't grown much over the last few mos. so thinking about having him fixed. Know they're suppose to be susceptible to prostate cancer the longer we wait. Wanted to wait till he quit growing and seems like we're there.
Know someone will give a good answer here. Love the "bay window" thingy!LOL

The longer you wait, the LESS susceptible to osteosarcoma (bone cancer) they are, as well as lymphoma, and hemangiosarcoma.

Most breeders recommend that you not neuter the boys until between the ages of 18-24 months. This allows the growth plates to fully close before neutering. If you neuter them before the growth plates close, you may end up with a taller, lankier mastiff than if you wait as they need the hormones in order to reach their full growth potential.

Most vets are either unfamiliar with the growth of giant breed dogs, or they advocate neutering at a young age in order to prevent unw
